摘要
本研究取正常胎儿12周至成人的颞骨234个,做组织切片,在显镜微下观察蜗小管的胚胎发育和生后变化。结果表明,蜗小管内口、外口、宽度和长度随胚胎发育而增加。生后1岁蜗小管的长度已达成人蜗小管的长度。儿童蜗小管较成人者宽。根据蜗小管形态的年龄特点,讨论了其发育规律、生理功能及临床意义。
The development of the cochlear aqueduct and its aging change were investiga-
ted in 234 temporal bones,ranging from 12-week-old embryo to adult by the light
microscope.The width of inner and outer opening,width and length of the
cochlear aqueduct were parallel with the advance of fetal age.The length of the
cochlear aqueduct at one year old was about the length of adult cochlear aqueduct.
The diameter of the cochlear aqueduct at the child was wider than that of the
adult.On the basis of morphology of the cochlear aqueduct and its characteristic
of age,the developmental rule of the cochlear aqueduct,its function and clinical
significance were discussed.
